Pin Definitions of Extensible connector
  Banana Pi has multiple extensible connectors for users to develop their own amazing projects and applications.   Most of common extension accessories Including LCD panel, touch screen, camera module, UART console and GPIO control pins are accessible from Banana Pi on-board connectors and headers.
 
 Banana Pi extensible 26-pins GPIO headers
  Banana Pi has 26-pins GPIO headers to extend the functions such as I2C, SPI, 5V and 3.3V output…etc.   There are also additional GPIO pins available for extension controls and daughter boards.  For instance, you can use those headers to connect an Arduino board for your projects.  Here could be the start point for your way of exciting applications. 

 
CON3 (GPIO Headers)
  CON3 is a DIP-26 headers.  The header pin definitions of CON3 are shown as below.
You can connect the headers for I2C, UART, SPI connections.  The 5V and 3.3 V power output are also available here.  Meanwhile, there are several pins free for GPIO pins for your specific usage.
